Troubleshooting 802.1X

Web browser users cannot be redirected correctly

Symptom
Unauthenticated users are not redirected to the specified redirect URL after they enter external
website addresses in their Web browsers.
Analysis
Redirection will not happen for one of the following reasons:
•
The address is in the string format. The operating system of the host regards the string as a
website name and tries to resolve the string. If the resolution fails, the operating system sends
an ARP request, but the target address is not in the dotted decimal notation. The redirection
feature does redirect this kind of ARP request.
•
The address is within a free IP segment. No redirection will take place, even if no host is present
with the address.
•
The redirect URL is not in a free IP segment.
•
No server is using the redirect URL, or the server with the URL does not provide Web services.
Solution
To resolve the problem:
1. Enter a dotted decimal IP address that is not in any free IP segments.
2. Verify that the access device and the server are configured correctly.
3. If the problem persists, contact Hewlett Packard Enterprise Support.
